Letters PatentNo. 84,715, Za-ted December 8, 1868.

To all whom it ma/y concern:

Be it known that I, M. W. STAPLES, of Catskill, in the county of Greene, and State of ANew York, have -invented andmade acertain new and useful Improvement in Wash-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the said'invention, reference being had to the annexed drawing, making part of .this speci'cation, wherein- Figure 1 is a vertical section of -a boiler fitted with my improvement.

Figure 2 is a plan of themovable bottom and circuf lating-tubes detached.

Similai` letters denote the same parts.

Heretofore wash-boilers have been made. with a perforated bottom, and with arising tube, for allowing the boiling water to circulate up through said tube, and be ejected upon the surface of the. clothes, returning through the same to the space below the movable bottom.

'llie nature of my present invention consists in a conical tube, that is airixed4 to, the movable bottom, and receives the circulating heated Water, and concen trates the same at the point where it is ejected upon the clothes from perforations in the sides of the upper portion of the conical tube.

The movable bo ttom stands' upon hollow legs or supports, througlf-which the water passes'to the bottom of the Washboiler, and emerges through openings in the side of the tubular legs.

In the drawing, l

a represents the bottom, and b, the sides of any usuaLwash-boiler.

c is a plate, of a shape to it the inside of the boiler, so as to be easily taken out or replaced. This plate may be of either wood or metal.

dri-'are 'tubular legs,'supportng the plate c, and provim with openings Hearthe lower end ofA each leg,

formed by removing a portion of the side ofthe tube, as seen at 2.2. v i

These tubnlarlegs serve to return the water to the space below the plate c, in order that the necessary circulation 'of heated water may be maintained vand promoted. I v' p Y The rising conicaltube e isY attached, at its larger end, to the plate c, around an .opening therein, corresponding, or nearly so, to the size of theV interior of the tube e; and at the upper or smaller end of this tube e are openings, 3 3, through which the circulate ing water is ejected by the action ofthe heat and steam, causing a column of water to rise and pass out upon the clothes, and then circulate down through the clothes contained in the boiler.'v f

This conical tube e is much stronger than the straight tube heretofore. employed, the clothes do not become entangled by twisting around the same, and are easily freed from the conical pipe by simply lifting them up, and, the base ofthe tube being large, causes the heated Water to iiow in. rapidly, and rise, so that the speed of the circulation is promoted, and the facility for introducing and removing the clothes is not lessened.

What I claim, and desire to secure by Letters lat-v ent, is-

The tubular legs d, supporting the removable bo tom, c, and provided with openings inther sides, near the lower ends, in combination with a tube, rising above the bottom, c, through which the rising 'water circulates, substantially as setforth.

In witnesswhereof, I have hereunto set my signature, this 1st day of August, 1868.
